Use special-shaped stone turn-milling machining center (HTM50200) to achieve the production of complex relief. Through the ArtCAM establish the three dimensional relief model of Riverside Scene at Qingming Festival. Analysis of blank material characteristics and features of NC machining center, select the appropriate tool, calculate cutting depth 、cutting speed 、feed rate 、spindle speed and other process parameters by formulas. With ArtCAM/CAM module to make process of the preparation of the rough finishing, the semi-finishing and finishing, and then generate the tool path file. Simulation in VERICUT can optimize the potential collision, over-cutting and owe cut of the machining process, and the adoption of special-shaped stone machining center for milling to finalize production of the relief, summarize the experience in special-shaped stone processing.

Five Axis

This paper studies the five-axis NC machining simulation process for four-blade propeller. Three-dimensional solid model of four-blade propeller is created based on UG, and then the tool path is generated using its CAM module, and finally the machining simulation is implemented on FIDIA five-axis machining center based on VERICUT. The correctness of NC machining process is verified. The method of the virtual simulation is also suitable for similar parts machining.

Cnc Machining Center

Aiming at the problem that current CNC incremental forming technology can’t directly manufacture the sheet-metal part with non-horizontal end face, the method that can manufacture this kind of sheet-metal part by using the equidistant tool path parallel to the sheet metal was proposed in this paper, in which the support and sheet metal was made together and sheet metal was directly fixed on the support. In addition, the equidistant tool path parallel to the sheet metal was generated using UG software and the sheet-metal part was fabricated by using vertical CNC machining center.

Cnc Machining Center

A method is presented for producing long-cone-distance spiral bevel gears using CNC machining center. Due to long-cone-distance, these spiral bevel gears are very difficult to produce, because machine-tool settings exceed the outermost limits of the available dedicated machines. The method removes the limits of the dedicated machine tool. This paper consists of (a) geometric modeling of the long-cone-distance spiral bevel gears, (b) process planning for NC machining based on CAM software. Experimental cuts were made to ascertain the validity and effectiveness of the presented method with a CNC machining center.

Abstract In this paper, a methodology of applying convex hull property in solving the tool interference problem is presented for 5-axis NC machining of free-form surfaces. Instead of exhausted point-by-point checking for possible tool interference, a quick checking can be done by using the convex hull constructed from the control polygon of free-form surface modeling. Global tool interference in 5-axis NC machining is detected using the convex hull of the free-form surface. A correction method for removing tool interference has also been developed to generate correct tool path for 5-axis NC machining. The inter-surface tool interference can be avoided by using the developed technique.
